This is the only example I have seen of a disc with mixed Technidisc mint markings. Side one has the markings that were used during the plant's later period, with the small lettering and the Technidisc name clearly displayed. Side two, however, has the markings used during the plant's earlier period, with larger characters and the Technidisc name completely absent.

The same film was released in Hong Kong under the alternate title "Underground: An Urban Nightmare" as [LILD0046].
